1 Claim.

This invention relates to conductor pipe hooks.

and methods. of making the same;

It is the principal object of the present invention tio provide animproved conductor pipe, hook which is rigid and which isparti'cularlysuitable for retaining plain or corrugated, rain spouting and the likefrom slipping" with respect to the conduct-or'band'.

It is a further object of the present invention to provide a conductor.pipe hook which is capable of permanent attachment to the pipe.

It is a further object of the" present inventionto provideaconductor-pipehook having an improved drive which is adapted formounting and gripping in either wood or-masonry; as desired.

It is a further object of the present invention to provide a conductorpipe hook having improved provisions for securing the same in place in awall, or the like.

It is a further object of the present invention to provide improvedmethods of making conductor pipe hooks of the character aforesaid.

It is a further object of the present invention to provide improvedmethods of forming conductor pipe hooks in which the strength of the Imaterial is retained after formation of the pipe hook and in certainrespects enhanced.

Other objects and advantageous features will be apparent from thespecification and claim.

The nature and characteristic features of the invention will be morereadily understood from the following description, taken in connectionwith the accompanying drawings forming part hereof, in which:

Figure 1 is a view in perspective of a unit length of channel sectionfrom which the conductor pipe hook in accordance with the presentinvention is formed;

Fig. 2 is a perspective view showing one stage in the formation of theconductor pipe hook;

Fig. 3 is a perspective view showing another stage in the formation ofthe conductor pipe hook;

Fig. 4 is a perspective view showing certain of the bending operationsat another stage in the formation of the conductor pipe hook;

Fig. 5 is a view in perspective of one form of completed conductor pipehook;

Fig. 6 is a view in perspective showing another form of completedconductor pipe hook;

Fig. '7 is a fragmentary elevational view illustrating certain of thedetails of the conductor pipe hook between the band and the drive; and

Fig. 8 is a fragmentary sectional View taken approximately on the line8-8 of Fig. '7.

Bike numerals refer to likepartsnthroughouta the severalviews.

It should, of course, be: understood that the description and drawings.herein are illustrative A merely; and that various modifications; and?changes may be madein the structure disclosed without departing fromthespirit of thevinuene tibn".

Referring now: more particularly to; the drawei'ngs, there isillustrated in- Fig: 1, aunitlength: of channel it from which. theconductor: pipe; hook is made; the channel. preferably: being; Qiiwrought steel rolled to the desired cross; seetion and withv a. web litand flanges l2; The

- length. of channel as is; preferably out; from. a.

longer piece in any desired manner.

As the initial steps to be performed on the length of channel, and asindicated in Fig. 2, one end l3, which is to form the terminus of theband of the hook, is preferably rounded and portions of the flanges l2adjacent thereto are cut away. At the other end M, which is to form thedrive of the hook, the flanges I2 are cut away and the terminus I5 ofthe end 14 is formed into a blunt chisel shape.

The flanges l2 and the web H intermediate the midportion of the unitlength of channel Ill and the terminus l5 are tapered as at It withrespect to the longitudinal axis and inwardly towards the terminus I5.At any preferred stage during the formation of the conductor pipe hook,and preferably while the ends of the unit length of channel Ill arebeing formed, a plurality of holes l3 are preferably provided in the webll of the unit channel I!) and extending therethrough for purposes to beexplained. As a further stage in the formation of the conductor hook,the flanges 2 at the section M are preferably fiattened and spreadinwardly into contact with each other as illustrated at E9 in Fig. 3 tocomplete this portion of the conductor hook.

The unit length of channel [0 is then bent, intermediate its ends, by amultiple bending as at 20, by which a short leg 24 of a portion H of theunit length It is disposed at an angle slightly less than a right anglewith respect to the remaining portion M of the unit length and alsotwisted through an angle of degrees so that, upon the completion of thebending, the longitudinal axis of the portion I1 is disposed in the sameplane as the longitudinal axis of the portion M of the unit channelpiece I0.

The band is then formed in the portion II beyond the leg 24 of thedesired shape and may be arcuate as indicated at 21 in Fig. 5 for usewith conductor pipes of circular or circular and corrugated crosssection, or may have a flat portion 22 disposed at right angles withrespect to the drive I4 as indicated in Fig. 6 with an end 23 disposedat 90 degrees with respect to the flat portion 22, for use withconductor pipes of square or rectangula cross section.

A conductor pipe hook is thus provided having a drive 14 with a chiselpoint l at the end for penetrating wood or masonry. The drive 14 has atapered portion adjacent the terminus l5 for engagement with the wood ormasonry in which the hook is to be mounted, and with a tapered recess oropen space 25 closed at one end by the flattened flanges 19, whichprovides a gripping channel for retaining the conductor pipe hook infixed engagement upon insertion.

The offset of the band 2| or 22 by the leg 24 from the longitudinal axisof the drive l4 provides for convenient access for hammering inalinement with the axis of the drive, thereby facilitating the insertionof the hook.

The interior of the band, eithe of arcuate shape, as illustrated in Fig.5, or of flat shape with an end hook, as illustrated in Fig. 6, providessurfaces for gripping engagement with the exterior of the conductorpipe. The holes 18 are provided for the insertion of self tapping metalscrews 26, which, by their engagement with the conductor pipe (notshown), prevent the conducto pipe from slipping or moving with respectto the pipe hook after assembly.

I claim:

A conductor pipe hook comprising a unitary length of channel having aband portion at one end with the flanges of the channel extendingtherealong on the interior thereof, a driving portion at the other endwith the flanges of the channel extending therealong, said drivingportion having a tapered terminal end portion with a blunt point and alongitudinally extending channel closed at the end adjacent the terminuswith the flanges in flattened relation to the web, and a connectingportion between said band portion and said driving portion, saidconnecting portion having the flanges of the channel extending along theinterior thereof, and said band portion having a plurality of spacedopenings through the web between the flanges for the reception offasteners for engagement with the conductor pipe.
